I have an Advanced Parental Controls subscription.

The Parental Control Bedtime time restrictions have stopped working.

I have it set to 7:00 PM - 2:00 PM daily.

This used to work, but
I recently noticed that my child was using Wi-Fi without the Wi-Fi restrictions.

When it was working properly, it would become "blocked" at 7:00 PM,
restricting usage, but it is no longer restricted.

What I've confirmed
* System Time
It's in the expected time zone (Tokyo). The time is synchronized correctly.
* Offtime
Not set
* Time Limits
It's set to 2 hours.
(I expect it to become blocked after 7:00 PM even if it's set to less than 2 hours.)
